The following formulas are available for the calculation:
J
x
= ¹/₁₂ × m(b
wt
² + l
wt
²)
J
x
=
Mass moment of inertia of the uniformly
distributed load
J
z
=
Steiner's displacement law
J
z
= m × d²
J
ges
= Total mass moment of inertia [kgm²]
m = Mass (including workpiece carrier) [kg]
J
ges
= J
x
+ J
z
b
wt
= Width of workpiece carrier [m]
l
wt
= Length workpiece carrier [m]
d =
Shift axis of rotation [m]
